Send Refresh Failure Notifications to Distribution List

[kpuhan]

It would be helpful to be able to set up a distribution list of those to send refresh failure notifications to. Currently, only the owner receives an email, but we have several administrators that require notification when certain reports fail.

This is also needed on Dataflows. Right now the only option is the dataflow owner, however, if that person is on vacation or sick then no other team members receive the notification.
